Individualized code interpretations help is available from RTAC and CTAC during business hours via phone (980-314-CODE and follow the prompts for technical assistance), via e-mail, or via walk-in at our offices, 2145 Suttle Avenue, Charlotte.

Note that all CTAC and RTAC code interpretations are limited to the information presented by the customer, and are subject to later verification that site conditions match the customer's description. Final code interpretations and requirements depend on actual site conditions, with field inspector interpretations taking precedence over RTAC or CTAC interpretations.
